Sitronix INTRODUCTION ST ST7586S 4-Level Gray Scale Dot Matrix LCD Controller/Driver ST7586S is a driver & controller LSI for 4-level gray scale graphic dot-matrix liquid crystal display systems. It contains 384-segment and 160-common driver circuits. This chip can be connected directly to a microprocessor which accepts 8-bit parallel interface (8080-series or 6800-series type), 4-Line serial interface or 3-Line serial interface. Display data is stored into an on-chip Display Data RAM (DDRAM). It performs the Display Data RAM read/write operation without external operating clock, and the power consumption can be minimized. In addition, since all necessary power supply circuits for LCD system are built-in, ST7586S constructs a LCD display system with the fewest components.

FUNCTION DESCRIPTION Microprocessor Interface Chip Select Input CSB pin is used for chip selection. ST7586S can interface with an MPU when CSB is "L". If CSB is H, the inputs of A0, ERD and RWR with any combination will be ignored and D[7:0] are high impedance. In 3-Line and 4-Line serial interfaces, the internal shift register and serial counter are reset when CSB is H. Interface Selection The interface selection is controlled by IF[3..1] pins. Please refer to the table below: Setting IF3 IF2 IF1 MPU Type Table 1 Interface Pin Function CSB A0 RWR ERD D[7:0] H H L Parallel 8080 series MPU /WR /RD A0 D[7:0] H L L Parallel 6800 series MPU R/W E CSB L H H Serial 4-Line series MPU -- -- D1=A0; D0=SDA. D[7:2] are not used. SCL L H L Serial 3-Line series MPU -- -- D0=SDA. D[7:1] are not used. Note: The un-used pins are marked as -- and should be fixed to H by VDD1. Parallel Interface When parallel interface is selected, the interface transmission type will be determined by the combination of the control signals. Please refer to the table below: 8080 series MPU 6800 series MPU /WR /RD R/W E Table 2 A0 CSB Interface Transmission Type H L L Write Command H L H Write Display Data or Parameter L H H H Read Display Data or Parameter Start H H H Note: Reading Display Data or Parameter is specified by the instruction before the read operation. Read Display Data or Parameter Stop Serial Interface In serial interface mode (4-Line or 3-Line), IC is active when CSB is L. Control signals (SDA, SCL and A0 for 4-Line) are enabled when CSB is L. When CSB is H, the MPU interface is not active and the internal shift register and counter are reset. It is recommended to set CSB to H after each byte transmission. In 4-Line serial interface, A0 signal is latched at the 8 th rising edge of the SCL signal (refer to Fig. 1). Fig. 1 Write-Operation of 4-Line Serial Interface Ver-1.1a 16/63 2009/11/30
In 3-Line interface, A0 signal is not available and the 1 st output of SDA will be treated as A0 flag (refer to Fig. 2). Fig. 2 Write-Operation of 4-Line Serial Interface Ver-1.1a 17/63 2009/11/30
Display Data RAM (DDRAM) ST7586S containing a 384x160x2 bit static RAM stores the display data. The display data RAM (DDRAM) stores the pixel data of the LCD. The built-in DDRAM is an addressable memory array with 384 columns by 160 rows. ST7586S provides two kinds of display modes (monochrome mode and 4-level gray scale mode) and a fast-addressing mode for fast updating display data. Each column address represents 3 sub-columns. For example, setting the column address to 01h means that upcoming 8 bits data is addressing to column 3; column 4 and column 5 respectively (refer to Fig. 3 and Fig. 4). The display data which is written by MCU will be stored in DDRAM with the format of D7 at the left and D0 at the right when MX=0 (refer to Fig. 3 and Fig. 4). The row address is directly related to the row output number. The LCD controller reads the pixel data in DDRAM, and then it outputs to COM/SEG pad. While the LCD controller operates independently, display data can be written into DDRAM at the same time and data is also being displayed on LCD panel without causing the abnormal display.

Addressing In order to allow MCU accessing display data continuously, the address counter is automatically increasing by one (+1) after accessing each byte of display data (i.e. White Display Data in all interface or Read Display Data in parallel interface). The locations of RAM are addressed by the address pointers (XS, XE, YS and YE). The address ranges are X=0~127 (column address) and Y=0~159 (row address). Addresses outside these range is not allowed. Before writing to DDRAM, a window must be defined for the incoming display data. By specifying the address pointers XS, XE, YS and YE, a window is established. The instruction registers XS and YS identify the start addresses while XE and YE identifying the end addresses. For example, the whole display range will be written via the following values to define 384x160: XS=0 (00h), YS=0 (00h) and XE=127 (7Fh), YE=159 (9Fh). Column Address Circuit The column address of DDRAM is specified by the Set Column Address instruction. Each column address includes three sub-columns Column N, Column N+1 and Column N+2 respectively ( N is the column address value). The column address counter is increased by one (+1) after each byte of display data accessed (write/read). The starting column address is defined by XS and the ending column address is defined by XE. The column address counter will be returned to the starting column address (XS) immediately if the increment of the column address exceeds the boundary column address (XE). Row Address Circuit The circuit provides the row address of DDRAM. The row address is increased by one (+1) after the column address counter is over XE. The row address will be returned to starting row address (YS) immediately when the row address is increased by one over the ending row address (YE). Ver-1.1a 20/63 2009/11/30

Partial Display This function is defining the visible display area as illustrated in Fig. 8. The different partial display area setting will be changing frame rate or Vop to avoid abnormal display. The recommended range of partial display area setting is defined from 64 duty to 160 duty. The partial display setting is combining the instructions of Partial Display and Partial Display Area. Display Area Display Area Display Area Fig. 8 Partial Display Definition Rolling Scroll This function is determined by the instructions of Scroll Area and Start Line. TA, SA and BA meaning Top Area, Scrolling Area and Bottom Area respectively. The instruction of Scroll Area setting must correspond to TA+SA+BA=160.

Liquid Crystal Driver Power Circuit The built-in power circuits generate the voltage levels which are necessary to drive the liquid crystal. It consumes low power with the fewest external component. The built-in power system has voltage booster, voltage regulator and voltage follower circuits. Before power ST7586S is OFF, a Power OFF procedure is needed. Please refer to the OPERATION FLOW section. External Component of Power Circuit The recommended external power components need only three capacitors. The detailed values of these three capacitors are determined by panel size and loading. Fig. 10 Power Circuit Ver-1.1a 24/63 2009/11/30
Temperature Gradient Selection Circuit SET V0 with temperature compensation (Temperature 24 C) There are 16-line slopes in each temperature step, and customer can select one line slope of temperature compensation coefficient for each temperature step. Each temperature step is 8 C. Please see Fig. 11 as below. Fig. 11 Temperature Compensation Coefficient Selection In instruction Temperature Gradient Compensation each parameter MTx, where x=0, 1, 2,, E, F has a setting value between 0 and 15. MTx=0 results in Mx=0V increment on V0, MTx=1 results in Mx=5mV increment,, MTx=15 results in Mx=15x5mV=75mV increment. Note that each MTx individually corresponds to a temperature interval; the Mx means temperature gradient slope coefficient. The relations between Mx and V0 quantity due to temperature V0(T) are described in the equation shown in Table 3.

Item Symbol Requirement Description VDD2 power ON delay t ON-V2 No Limitation VDDI and VDDA can be applied in any order. IC will NOT be damaged when one of VDD1 and VDD2 is ON but another is OFF. Power stable is defined as the time that the later power (VDDI or VDDA) reaches 90% of its rated voltage. Recommend Setting: -50ms t ON-V2 No Limitation. Case-1 RESB=L can be input at any time after power is stable. RESB input time t ON-RES t RW t ON-RES t RW & t R should match the timing specification of RESB. Case-2 RESB has priority over CSB.

If the contents of internal registers are the same as default, the related commands can be ignored. 2. If RESB is held high or unstable during power ON, a successful hardware reset by RSTB is required after VDDI and VDDA are both stable (as illustrated in Case-2).
